The key benefit of PDF::Reuse is the ability to load an existing PDF file and use this as the basis for a new document.

For example, to produce receipts or shipping labels you could create a blank receipt in Microsoft Word, convert this to PDF, then use PDF::Reuse to add in details such as the order number and customer address.

If the PDF filename is not specified, it will be set to the last component of the URL path, appended with '.pdf'. For example, with a URL of http://localhost/view/order/pdf/1234 the PDF filename would be set to 1234.pdf.
